We reviewed 34 hindquarter amputations performed for malignant tumours around the hip from 1971 to 1988, classifying them as palliative or curative according to the resection margins or the presence of disseminated disease at the time of surgery. There were three peri-operative deaths, 12 palliative and 19 curative procedures. Ten patients died of disseminated disease within a year of surgery, eight of whom had had a palliative operation. Three patients died between one and five years after palliative surgery. One died of unrelated disease at nine years. Seventeen patients are disease free an average of 31 months from surgery, 16 after curative procedures. The median survival after palliative amputations was six months and the 5-year survival rate for curative cases was 83%.
